Power Converter: Convert Between Watts, Horsepower, BTU/hr, and More

Introduction

Power measurements are everywhere � from light bulbs and car engines to industrial machinery. Our power converter handles all major power units.

Conversion Formulas and Factors

The watt is the SI base unit for power:

1 kW = 1000 W 1 MW = 1000 kW 1 hp (mechanical) = 745.7 W 1 hp (metric) = 735.5 W 1 BTU/hr = 0.293071 W kW to hp: hp = kW � 1.34102 hp to kW: kW = hp � 0.7457

How to Use the Converter

Our power converter supports all common units. For example, 100 hp = 74.57 kW.

Real-World Examples

Automotive: A car with 200 hp produces 149.14 kW. Appliances: A 1500 W space heater uses 1.5 kW. Industrial: A 500 kW generator = 670.5 hp.

Common Applications

• Automotive: Comparing engine power across measurement systems
• Electrical Engineering: Designing power systems and load calculations
• HVAC: Sizing heating and cooling equipment by BTU/hr
• Manufacturing: Specifying motor and machinery power
• Energy Management: Monitoring and optimizing consumption

Tips for Accurate Conversions

1. 1. Distinguish mechanical hp (745.7 W) from metric hp (735.5 W)
2. 2. For electrical power: P = V � I for DC circuits
3. 3. Apparent power (VA) differs from real power (W) in AC circuits
